Cyclic tasks
Interrupt tasks (Power OFF interrupt tasks, scheduled interrupt tasks, I/O interrupt tasks, and external
interrupt tasks)
Cyclic tasks: 128
Interrupt tasks: 256
(Interrupt tasks can be defined as cyclic tasks to create extra cyclic tasks. Therefore, the total number of
cyclic tasks is actually 384 max.)
• Local symbols: Can be used only within a single task in the PLC.
• Global symbols: Can be used in all tasks in the PLC.
• Network symbols (tags): I/O memory in the CPU Unit can be externally accessed using symbols,
depending on parameter settings.
• BOOL (bit)
• UINT (one-word unsigned binary)
• UDINT (two-word unsigned binary)
• ULINT (four-word unsigned binary)
• UINT BCD (one-word unsigned BCD)
• INT (one-word signed binary)
• DINT (two-word signed binary)
• LINT (four-word signed binary)
• UDINT BCD (two-word unsigned BCD)
• ULINT BCD (four-word unsigned BCD)
• REAL (two-word floating-point), LREAL (four-word floating-point)
